I usually put this info on my label:
"A world of ladybugs" .....made by Jane Doe in Feb 2008 for Jack Pratt to celebrate his 100th birthday.
Pattern: quilterscache.com, pieced corners of science
Quilted by: Me; Address.....state or ???
Or whatever.....if it's a donation quilt I don't put my full name on it.
Sometimes I do a phototransfer on the label, sometimes I just write it with pigma permanent marker after ironing the fabric to freezer paper to stabilize it, sometimes I use bubblejet set & do a picture I've found on the net someplace as the background, and then put the writing over it all.
Think about quilts we see today from the past, and what do we want to know about them, and then try & put that info on YOUR label.....just my input.
